Definitions
- the present invention relates to the communication field, and more particularly, to a method and apparatus for rank self-adaptation.
- the multi-input multi-output (MIMO for short) technique is a wireless transmission technique using multiple ( N T ) transmitting antennas and multiple ( N R ) receiving antennas. It can effectively improve the capacity and the link transmission performance of a wireless network.
- the value of N S is determined by the relativity of the MIMO channels.
- N S at a User Equipment (UE for short) side is called as a rank
- N S at a network side is called as a layer.
- the UE needs to feed back ranks of the MIMO channels to the network side, which performs rank self-adaptation processing based on the ranks fed back by the UE.
- a simple rank self-adaptation processing method is that the network side controls the number of the independent channels sending downstream data based on the newly reported rank ( N S ) at the UE side. As the ranks of the MIMO channels change slowly, this method enable the network side to well self-adapte the rank change of the MIMO channels.
- the difference between the newly reported rank at the UE side used by the network side and the rank of the current actual MIMO channel may be greater such that spatial advantages of the MIMO will be given a great discount.

- the apparatus may further have the following features:
- the apparatus further comprises a user equipment position measurement unit connected to the rank determining unit, wherein the user equipment position measurement unit is configured to measure whether a user equipment is located at the edge of a cell to which the user equipment belongs; the rank determining unit is further configured to: when determining that the number of the ranks in the rank receiving window is greater than the threshold A and the distribution state of each rank in the rank receiving window at the current moment is state 3, state 3 meaning that the ranks in the rank receiving window in turn are continuous x and one y , the absolute difference value between y and x is m, m is greater than or equal to 1 and is less than or equal to N max S -1, and N max S is the smallest value among the number of the receiving antennas and the number of the transmitting antennas, when determining that the difference value between y and x is less than 0, take the newly reported rank in the rank receiving window as the rank at the current moment; when determining that the difference value between y and x is greater than 0, obtain information whether the user equipment is located at the edge of a
- the apparatus also comprises a user equipment position measurement unit connected to the rank determining unit, wherein the user equipment position measurement unit is configured to measure whether the user equipment is located at the edge of the cell to which the user equipment belongs; the rank determining unit is further configured to: when determining that the number of the ranks in the rank receiving window is greater than the threshold A and the distribution state of each rank in the rank receiving window at the current moment is state 4, state 4 meaning that the ranks in the rank receiving window in turn are continuous x and y, x is not equal to y, the number of y is less than the number of x , and the number of y is greater than or equal to n, and n is greater than or equal to 2, when determining that the value of y is less than x, take the newly reported rank in the rank receiving window as the rank at the current moment; when determining that the value of y is greater than or equal to x, obtain information whether the user equipment is located at the edge of a cell to which the user equipment belongs from the user equipment position measurement unit, and determine the rank

- the used determining method is the same as that described in the following rank self-adaptation method.
- the method for rank self-adaptation comprises the following steps.
- Step 201 a base station receives ranks reported by a user equipment via a rank receiving window.
- the length (Trank) of the rank receiving window can be defined as a fixed length, or can be defined as a multiple of a reporting period of a fixedly received rank.
- the value of the Trank is from 50ms to 1000ms, or is N times of the reporting period of the rank, and the value range of N is an integer from 3 to 12.
- the length of the rank receiving window is defined as 200ms or 3 reporting periods of the rank.
- the length of the rank receiving window can be determined based on the smallest value N max S among the number of receiving antennas and the number of the transmitting antennas, the greater the value of the N max S is, the greater the value of the length of the rank receiving window is.
- the processing procedure of the rank receiving window is shown in FIG. 3 , in which the reporting period of the rank is set to be 4 transmission time intervals (TTI for short), N is set to be 4, namely, the length of the rank receiving window is 12 TTIs, and the rank receiving window slides by taking time as its axle.

- N 4 transmission time intervals
- the rank receiving window slides by taking time as its axle.
- Step 202 the base station determines the rank at the current moment based on the distribution state of each rank in the rank receiving window at the current moment, and determines the number of independent channels used for sending downstream data to the user equipment based on the rank at the current moment.
- State 2 (or called as a slow change state) means that when N max S is greater than or equal to 2 and is less than or equal to 7, distribution of each rank in the rank receiving window meets the following conditions: the ranks in the rank receiving window in turn are continuous x and continuous y , namely, ⁇ x,..., x, y..., y ⁇ , values of x and y differ by 1, where x , y ⁇ ⁇ 1, ⁇ , N max S ⁇ , and the number of y is greater than or equal to the number of x ; when N max S is equal to 8, distribution of each rank in the rank receiving window meets the following conditions: the ranks in the rank receiving window in turn are continuous multiple x and continuous multiple y and continuous multiple z , namely, ⁇ x ,..., x, y, ...,y, z ,...
- State 3 (or called as a sudden chage state) means that distribution of each rank in the rank receiving window meets the following conditions: the ranks in the rank receiving window in turn are continuous multiple x and one y , the absolute difference value between y and x is m, x, y ⁇ ⁇ 1, ⁇ , N max S ⁇ , 1 ⁇ m ⁇ N max S -1.

Under statue 4, when the value of y is less than x
- the newly reported rank in the rank receiving window is taken as the rank at the current moment; when the value of y is greater than or equal to x (indicating that the shear direction of the rank is increase) and the user equipment is located at the edge of the cell to which the user equipment belongs, 1 is taken as the rank at the current moment; when the value of y is greater than x and the user equipment is not located at the edge of the cell to which the user equipment belongs, the newly reported rank in the rank receiving window is taken as the rank at the current moment.
- Whether the user equipment is located at the edge of the cell to which the user equipment belongs in state 3 and state 4 may be determined based on reference signal received power (RSRP for short) of the cell reported by the user equipment. For example, when the RSRP of the cell reported by the user equipment is less than or equal to a RSRP threshold a, the user equipment is determined to be located at the edge of the cell; when the reference signal received power of the cell reported by the user equipment is greater than the RSRP threshold a, the user equipment is determined to be not located at the edge of the cell.

- the threshold m used for determining whether the rank is sudden change is 1, and the threshold n used for determining whether the rank is shear is 2.
